 Currently every post that is in the list have to be online too, which isn't a problem
for most feeds, but for some not. It would be nice when the posts are also stored local,
so that when they vanish from the online list they don't vanish from the menu.
I thought about a simple database to save the parsed feeds or and additional list for
unread feeds and a corresponding cache file.
